If you're looking for more storage and a higher resolution display, the Razer Blade 14 is better, though it comes at a premium price and may deliver slightly shorter battery life due to a smaller battery capacity. On the other hand, the Lenovo Legion Slim 7 is a more budget-friendly option with a larger screen and longer battery life, but with less storage and a lower resolution screen. The Razer has a more powerful main processor and graphics card, making it more suitable for intensive gaming, 3D rendering, and machine learning tasks. However, the Lenovo offers significant cost savings and still provides solid performance for general use, gaming, and engineering tasks, albeit with slightly less potent hardware compared to the Razer.

The Razer Blade 14 has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo Legion Slim, with its high resolution and bright display, caters well to daily tasks and professional design work, where sharpness, clarity, and color accuracy are crucial. Razer Blade 14's high-resolution screen also offers wide color gamuts, essential for precision in engineering and graphic design, ensuring that colors are represented faithfully. However, both laptops fall short for 3D applications and gaming, as they lack high refresh rates necessary for fluid motion and fast-paced visuals, which are key to an immersive experience in these areas.

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."

Allen Ngo | May 2022
"After making a huge splash with the original 2021 model, it's expected that the 2022 refresh would be more of a minor update to an already impressive machine. It adds a higher resolution webcam (720p to 1080p), faster CPU (Ryzen 9 5900HX to Ryzen 9 6900HX), faster GPU (RTX 3070/3080 to 3070/3080 Ti), faster RAM (DDR4-3200 to DDR5-4800), faster M.2 SSD support (PCIe3 x4 to PCIe4 x4), newer WLAN module (Killer AX1690i to Qualcomm WCN685x), and a MUX switch for the new integrated Radeon 680M GPU. It's indubitably an upgrade especially in terms of single-thread processor performance."
